FreeBSD 8.0-RELEASE-p2
Python 2.5.5
amd64
attached diff provides a test for cpickle which reproduces a segfault when pickling >15 nested dicts in a threaded environment
cpickle.patch attached to http://bugs.python.org/issue3640 applys cleanly to the 2.5 source and fixes this issue
i understand 2.5 is no longer maintained except for security fixes, i leave it up to the maintainers to decide if this segfault warrants a security patch
thank you
